TO ALL WHOM IT MAY CONOERN:

13e it known that I, JOHN RADDIN, of Lynn, in the county of Essex, and State of Massachusetts, have invented'an Improvement in Carriage-Wheels; and I do hereby declare that the following, taken in connection with the drawings which accompany and form part of this spccicatiomis a description of my invention suiiicient to enable those skilled iu the'art to practise it.

The invention relates to that class of'carri'age-wheels each having a. metal felloe or felloes; and consists in constructing such wheels with felloes made of wrought-metal tubes, the outer surfaces of which are'attencd to form the tread of the wheel, or the surface to which a tread or tire may be applied.v

The invention is particularly applicable to carriage-Wheels in which rubber dr elastic cushions are used in connection with the spokes and rim of the wheel, (as scen in my patent bf June 13, 1865,) the tubular felloc forming a convenient and desirable receptacle for containing the 'heads of the spokes, and the elastic cushions applied thereto, with the cylinders or boxes in which the heads of the spokes and the cushions play.

The drawings represent, at A and B, respectively, a cross-section and alongitudinal section of a portion of a wheel-felloe or rim embodying the invention, the sections being taken centrally through the felloe-end of one y of thespokcs.

a denotes' the felloe or rim, b one of the spokes. The felloe is tubular, as shown, being made from a wroughtmetal tube or pipe, compressed at the sides, if desirable, and flattened at the outer surface. This outer surface may constitute the tread of the wheel, as before stated, but generally I prefer to apply thereto a. steel tire, c, secured to the felloe by bolts cl and nuts e. Where the elastic cushions are used in connection with such felloe, the arrangement preferred is as follows: The outer end of each spoke Works through the inner end of a box or cylinder, f, at the bottom of which box is a rubber block or cushion, g', placed under the head of the spoke, or

under a washer applied thereto. Over the head another cushion, L, is shown, and both may be used, or either one, as may be deemed desirable, the strain coming upon the rubber as the rim expands or contracts radially, the same as shown in my aforesaid patent, and in modifications thereof made by me. Where the tire c is used, the boxes or cyliudersf may be entered through the upper surface of the felloe, and the lower end of each be contracted, and extended through a hole bored through the inner side of the fclloe, as seen in thedrawing, such arrangement enabling the cylinders to be applied with facility, and in such manner as to secure each in position, as will be readily understood. For the construction ofthe fcllce for wheels of light vehicles, I recommend the employment of wrought-iron gas'pipe.

I claim, in the construction of carriage-whe`els, making the felloe or rim thereof of Wrought-metal tube, the outer surfaceof which is flattened and surfaced by a tire, substantially as and for the purposes set forth.

Also, in combination with such tubular felloe, the elastic cushions, arranged to operate substantially as described.

JOHN RADDIN.
